Remove make preinstall
A speciality of the RTEMS build system was the make preinstall step. It
copied header files from arbitrary locations into the build tree. The
header files were included via the -Bsome/build/tree/path GCC command
line option.
This has at least seven problems:
* The make preinstall step itself needs time and disk space.
* Errors in header files show up in the build tree copy. This makes it
hard for editors to open the right file to fix the error.
* There is no clear relationship between source and build tree header
files. This makes an audit of the build process difficult.
* The visibility of all header files in the build tree makes it
difficult to enforce API barriers. For example it is discouraged to
use BSP-specifics in the cpukit.
* An introduction of a new build system is difficult.
* Include paths specified by the -B option are system headers. This
may suppress warnings.
* The parallel build had sporadic failures on some hosts.
This patch removes the make preinstall step. All installed header
files are moved to dedicated include directories in the source tree.
Let @RTEMS_CPU@ be the target architecture, e.g. arm, powerpc, sparc,
etc. Let @RTEMS_BSP_FAMILIY@ be a BSP family base directory, e.g.
erc32, imx, qoriq, etc.
The new cpukit include directories are:
* cpukit/include
* cpukit/score/cpu/@RTEMS_CPU@/include
* cpukit/libnetworking
The new BSP include directories are:
* bsps/include
* bsps/@RTEMS_CPU@/include
* bsps/@RTEMS_CPU@/@RTEMS_BSP_FAMILIY@/include
There are build tree include directories for generated files.
The include directory order favours the most general header file, e.g.
it is not possible to override general header files via the include path
order.
The "bootstrap -p" option was removed. The new "bootstrap -H" option
should be used to regenerate the "headers.am" files.
Update #3254.

score: replace current and real priority with priority node
Encapsulate the current_priority and real_priority fields of
the thread control block with a Thread_Priority_node struct.
Propagate modifications throughout the tree where the two
fields are directly accessed.
Updates #3359.

score: Introduce new monotonic clock
Rename PER_CPU_WATCHDOG_MONOTONIC to PER_CPU_WATCHDOG_TICKS. Add new
PER_CPU_WATCHDOG_MONOTONIC which is based on the system uptime (measured
by timecounter).
Close #3264.

beatnik, motorola_powerpc, mvme3100, mvme5500: Simplify bsp_specs
This collection of BSPs shared the linker script shared/startup/linkcmds.
I renamed that ot shared/startup/linkcmds.share and made a BSP family
specific startup/linkcmds. This was needed because each BSP family had
a different combination of start file name, undefined symbols, etc.
Updates #3520.

gen5200, gen83xx, gen83x, mpc55xxevb, psim, qoriq, t32mppc, tqm8xx, virtex: Simplify bsp_specs
These BSPs all use shared/startup/linkcmds.base and thus needed to be
modified at the same time. Variations in the arguments were reflected
into the BSP specific portions of the linkcmds.
Updates #3520.
